Transcriptome Profile Alterations with Carbon Nanotubes, Quantum Dots, and Silver Nanoparticles: A Review

Area of Science:

• Environmental toxicology
• Nanotechnology
• Molecular biology

Background:

• Engineered nanomaterials (ENMs) show promise in medicine but their persistence raises health concerns.
• Understanding ENM toxicity mechanisms is critical due to their long-term presence in the body and environment.
• High-throughput sequencing methods like RNA-Seq are vital for studying cellular responses to ENMs.

Purpose of the Study:

• To review and analyze transcriptomic changes induced by three specific ENMs: carbon nanotubes (CNTs), quantum dots (QDs), and silver nanoparticles (AgNPs).
• To synthesize current knowledge on the toxicity mechanisms and potential long-lasting health effects of these ENMs.

Main Methods:

• Cross-examination of existing publications focusing on transcriptomic data.
• Utilizing Next-Generation Sequencing (NGS) and RNA-Seq methodologies as primary research tools.
• Analyzing studies that measure changes in transcript levels following exposure to CNTs, QDs, and AgNPs.

Main Results:

• Transcriptomic alterations provide insights into the cellular responses and toxicity pathways of ENMs.
• Specific ENMs like CNTs, QDs, and AgNPs induce distinct patterns of gene expression changes.
• The long-term health implications of these transcriptomic changes remain an area requiring further investigation.

Conclusions:

• Transcriptomic analysis is a powerful approach for assessing ENM toxicity.
• Further research is needed to fully elucidate the long-term health risks associated with ENM exposure.
• This review highlights the importance of understanding ENM-induced molecular changes for risk assessment and safe application.
